My invention relates toan improved roofmg product and process of reducing same.

The invention relates to flexible roofing material, comprising a length of backing material such as paper, felt orthe like treated or saturated with asphaltum or other bituminous compound, to one of whose surfaces a granular surfacing material is applied.

The granular material is so applied as to form designs, as for example, an imitation of shingles, tiles or the like. 7 One of the objects of the invention is'to apply comminuted granular material to a plurality of fields or areas of the adhesive coated surface, and between these fields or areas to put a second granular material of a difierent color than the first. The aforesaid granular materials are preferably applied 1n symmetrically arranged designs and are non-adhesive substances which will adhere to the adhesive asphaltic coating or saturation previously applied to the foundation or backingj The first mentioned fields or areas of granular or comminuted material may be formed by applying to the adhesive asphalt powdered or flaked mica or comminuted graphite or comminuted pumice stone or the like, while the other fields or areas of comminuted nonadhesive material maybe sand, gravel or other crushed material but of a different color than the comminuted material formin the first fields or areas.

lhe first fields or areas may be applied, if desired, by the use of printing rollers as shown in the drawings, in which event if the second fields or areas are applied later, the second granular material will obviously not adhere to the fields or, areas which are already covered by the first granular material. It' is of course. essential that the two fields or areas referred to be of contrasting colors relative to each other inorder to get the desired efiect.

In the accompanyin drawings an ap paratus is illustrated siowingone way 111 which the process may be practised and the product produced.

Figure 1 is a side elevational view in we tical section showin the various mechanism links in the chain 05 operations;

Fig. 2 is an enlarged perspective view of the printing and abutment rolls between WhlCh the backing material passes after an.

application thereto of the adhesive surface;

Flg. 3 is a plan view of a section of the finished product, and Fig. 4 is a sectional view of such product. 1

Referring to Fig. 1, 10 and 11 represent upper and lower rolls, the upper roll being driven in any suitable manner as by a belt 12 driven from the shaft 13. The body or backing of the roofing material 14 is propelled through these rollers and has a coatmg' of adhesive material applied to its upper surface thereby. This coating material is shownas contained in a tank 15 in which it is heated by steam piping 16, a spout 17 delivering the material to the backing in advance of the upper roll so that as the rolls revolve this coating material is spread uniformly over the backing material so that an even coating results. Adjacent the out-- let end of the rolls 10 and 11 and in front of the backing emerging from such rolls is the printing roll 18, this roll being journaled in suitable supporting framework 19, and the roll being driven. as by belt 20 passing around a suitable pulley on drive shaft 13. Below this printing roll and below the backing is the abutment roll 21 also journaled in the framework 19. The printing roll has on and about its periphery the embossed or raised lines 22 representative of the outline of a pattern, the raised areas forming in this case outlines of shingles or tiles. Adjacent the printing roll is a trough 23 for containing the non-adhesive material 24 which may be powdered or flaked mica, graphite, pumice stone or any other non-adhesive material. Mounted to revolve in this trough is a roll 25 which dips into the material of the trough and also engages against the outer surfaces of the raised portions of the printing roll in order to apply adhesive substance to such surfaces. In order that the material will better cling to the embossed surfaces, these surfaces may be roughened or otherwise treated and the roll 25 may have a coat 26 of felt or bristles for better carrying the material a ainst the embossing surfaces. When the liacking 14 emerges from the rolls 10 and 11 the asphaltic sticky coating which was applied thereto by the rolls will beeagaged by the Specification of we... rum. 1 t t 191'? did crushed material or the like and this mate.

rial falls on the backing to progressively cover the entire top surface thereof, but such material will adhere only to the areassurrounded by the non-adhesive pattern .or design lines. After receiving thesecond granular material, the backing travels alon a distance until the adhesive coating has .1- cooled and hardened sufficiently. the backing; then being given a reverse bend about the upper and lower rollers 29 and 30 in order that the loose material may drop therefrom into the recertacle 31 from which it is conveyed away as y means of a screw 32. The backing then passes about lower and upper rolls 33 and 34: and then between pressure rolls 35 and 36, such pressure rolls forcing the wearing material more intimately into engagement with the sticky areas. After this latter treatment, the finished product may be rolled up into marketable rolls. Fig. 2 shows more in detail the operation and effect of the printing roli mech* anism, and Figs. 3 and 4 show sections of the finished product.

It may be desirable to face the. lower side of" the roofing backin for strengthening purposes, as for example by the application thereto of burlap. Such applicat on may be simultaneously performed with the other steps described above. The strengthening material 37 may be fed from a supplying roll 38 to the under side of the backing .to pass'therewith between the rolls IO-and 11. Below the roll 11 a trough 39 contains'ad hes-Ive material such as asphaltum which is heatedas by means ofsteam pipesiO. As the rolls 10 and Ill rotate the material from the pan39 is carried by the rolls 1-1 against theunderside of the material, 37 andwis forced through the' pores of said material against the under surface of the backing 14- the burlap or other strengthening material then securelyandsmoothly adhering to the backing. Before the backing 14: with the strengthening material 37 thereon reaches the printing roll, the outer face ofthe material 37 is preferably treated with, some non-adhesive substance in order that it will not stick to the abutment roll. A rotary brush 4:1 is therefore arranged between the rolls 1 0 and .11 and the abutment roll 21 for brushing non-adhesive substance against the material 3'2 This substance may be, the,

same substance that is used for forming the pattern lines, and is contained in a suitable trough 42- into''' which the brush dips.

The process is not limited to being made by the detaii mechanism shown except in so far "as any such limitations may be put in the appended claims, and the product is a product as such regardless of the mechanism by which it may be made.

I claim 1, Theprocessof producing roofing which consists in applying an adhesive coating to baekin material, then applying comminu-ted non-ad iesive substance to a plurality of fields or areas of the coated surface, and then applying contrasting-surfacing material to the interposed spaces of the coated surface.

2.

3. The process of producing roofing.whi.ch consists in propelling lengths of backrngrhaterial, a plying adhesive coating to one side of. said acking during propulsion thereof applying comminuted non-adhesive materia to said adhesive coating along lines or areas representative of pattern or design outlines, and applying a; contrasting surfacingmaterial to the coatin to adhere to the areas thereof not covered, y the-non-adhesive commi-nuted material; 7

a. A process of making prepared roofing, which consists of applying a bituminous'adhesive coating to a ength of flexible fabrie like material, applying comminuted non-adhesive material to a plurality of fields or areas of the coating symmetrically ar-. ranged designs, and applying comminnted nomadhesive material of a different color than the firstimentioned material'to other fields or areasofthe coating,

1/ 7. A flexible prepared roofing comprising a fabric-like foundation, an adhesive coating applied thereto and an exposed facing presenting a plurality of designs in simulation of tiles, or shingles, said designs being formed by contrasting adjacent areas, corresponding areas of one character being formed by granular material of one character applied directly to the adhesive coating and corresponding areas of another character being formed by different granular material applied directly to the adhesive coating.

8. A process 'of making prepared roofing which consists in applying an adhesive coathaving an appearance distinctive from the first mentioned material.
